# Tesla One vs Monterra.ai

The clearest difference is rating: Monterra.ai at 5.0 against Tesla One's 3.0. Tesla One's advantage is review sentiment (21% vs 0%) and ratings volume (310 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Monterra.ai holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Tesla One has 310 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 21% of Tesla One's written reviews are positive against 0% of Monterra.ai's, so the app with the better star average is not the one people write more warmly about.

Tesla One ships an update every 6 days, Monterra.ai every 3 weeks. The most recent releases landed on October 30, 2026 and October 10, 2026 respectively.
